I couldn't find any reference to this issue on other threads...
I'm running Vista 32-bit, ArmA 1.08 (Atari-US), 8800GTX. Nothing in the game seems to save... for instance, if I change video options, they are back to defaults the next time I start the game. If I play a mission, and save it at some point, the Load button is always disabled. Playing a Campaign, every time I re-load ArmA it puts me right back to Mission 1.
Any clues?
